Lidl Screenwash Alternatives?

Feel free to take it as whatever you wish. You can take it as wholehearted support for Donald Trump and David Icke, should it make you happy.

It was intended to be taken at face value, and face value alone.

So what has been your value add to this thread??

That can't happen.

If the air temperature is -5, the washer jets will cool down to -5 more quickly in moving air than static air, but they cannot chill below -5.

Wind chill causes humans and other living creatures to perceive that the air temperature is lower than it is because of the more rapid chilling effect of moving air on the body. We cool down more quickly in a cold wind than in static air and we feel that as a lower temperature.

But inanimate objects don't 'feel' temperature in the way that living creatures can.

Inanimate objects such as washer jets will tend to cool down to the ambient temperature of the surrounding air. Driving at 70 mpg increase the rate of heat loss but it doesn't cool the jets below ambient air temperature.

Once the washer jets have chilled to the -5 in your example, that temperature matches the -5 temperature of the surrounding air and will not go below it.

Well if thats the scientific answer, then cool.

However it still means your washer jets are exposed either directly or indirectly to air at -5 degrees.

I've had washer jets freeze on me on my previous long motorway commute many times - a good, sensibly priced screenwash solves that.

I'm terribly sorry for any deep personal offence you've taken at my scepticism about the uniqueness of the merits of your preferred brand of discount supermarket screenwash.

Also, whilst -5 might be a worse case temperature, the wind chill factor on your washer jets of doing 70MPH on a motorway when its freezing will take it beyond that, so you're looking often at frozen jets.

Wind chill is irrelevant to ananimate objects

TBH, they tended to be sold in the latter part of the year, Nov/Dec, rather than now, although I hadn't seen it at all so far. Good job I've still got 10L left from the previous year

It was very late last year, I remember thinking winter will be over.

I'm down to one more washer fill. Living in the sticks just adds so much hassle will check Amazon etc

Was that a deliberate pun?

Of course it does. I was just being a bit pedantic and picking up on the point that the laws of physics means that they cannot chill below ambient air temperature.

We should all use screen wash and anti freeze to safely cope with the lowest expected air temperature, plus a safety margin. We don't need to factor in an additional margin due to driving at 70mph.

Screen wash is less likely to freeze when the car is being driven than when parked due to conductive heating from the engine etc. We have all probably experienced frozen screen wash when we first start the car on a cold morning and finding it liquefies again soon after starting the engine and driving off.

Will give this a go and on offer at Europarts just now

I've never used it, because its not avail (to my knowledge) in Northern Ireland

I use Neilsen stuff which is great, but expensive.

BUT, i do know from comments on here and over on pistonheads, etc, that its VERY good, and cheap and that comes up year in year out. if you want to dismiss it because its from a discount supermarket then thats your loss.

I'm surprised you arent aware of that.

Ultimately i'm interested because in the absence of the LIDL stuff, i'm curious as to what people recommend thats good AND cheap.

That doesnt seem unreasonable to me - on a money saving forum?

Just surprised you seem so intent on poo pooing it.

I use halfords concentrate, its the only one available locally with bitrex.
